3-Flow Flange Isolation

General Information

The POINTGUARD™ sealing/isolating gasket system is designed for general applications where electrical flange isolation and corrosion control are required on pipes containing water/wastewater, gas, natural gas, oil and other hydrocarbon based medias up to 302ºF(150ºC). Available for flat face, raised face and ring type joint flanges from 1/2" to 120" (and corresponding API and DN diameters), ANSI 150-1500#, API 2-5K or PN20-250, the POINTGUARD™ gasket is an engineered value added solution for trouble free operation. The POINTGUARD™ sealing/isolating gasket system consists of a retainer with an incline-plane seal groove geometry designed to optimize each seal's elastic memory, in conjunction with a proven rectangular sealing element ("Quad" ring). This design guarantees low bolt load requirements and high sealing reliability. POINTGUARD™ systems are available with a variety of retainers and seal elements. 

A Fresh Look at Sealing - Design Features
A Fresh Look at Sealing - Design Feature: A non-spliced (one-piece) Teflon seal element, available from 1/2" to 24". Combining this seal with the incline-plane groove design is a first for this generation of gasket technology; an excellent choice for engineers and end users wanting increased seal integrity.
